To all whom it mag concern:

Beit known thatI, GEORGE G. KAISE a citizen of the United States, residing in Hare rison township, in the county of Clay and State of Indiana, have invented certain new and useful Improvements in Wood-Burning Stoves; and I do declare the following to be a full, clear, and exact'description of the invention, reference being had to the accompanying. drawings, and. to the letters and figures of reference marked'thereon, which form a part of thisspecification.

This invention'relates to heating stoves, especially of the kind that are adapted for use in dwellings, the inventionhaving refer-.

ence particularly to improvements in. stoves that are adapted for using wood for fuel, and for supplying heated air for heating rooms separate fromthe room in which the.

stove may be situated, and while heating the roomor apartment where the stove'may be located. 1

Objects of the invention are to provide an improved wood burning stove of simple-and cheapconstruction and adapted to serve the purpose of a hot air furnace while at the same time supplying heat for the apartment in which thestove may be located, and to.

provide a combination stove of the abovementioned character that will be durable and economical in use, and in whichvarious kinds of fuel may be used for producing heat.

The invention consists in a stove having an air chamber at the sides and top of'the combustion chamber, and draftfiues outside of. the air chamber and-serving as a heating jacket therefor, all of novel form and construction. And the inventionconsists further in the parts and combinations and arrangements of parts as hereinafter particularly described and defined in the appended claims.

Referring to the drawingsFigure. 1 is, a front elevation of the improved stove; Fig.

2-, a longitudinal vertical central sectional view; Fig. 3, a transverse sectional viewon the line A A in Fig. 2, looking forward; Fig. 4 a rear elevation of the stove; Fig. 5,. a fragmentary plan. viewof one of the draft shutters or gates comprised in the construction of the stove; Flg. 6, a frontelevation of a modified form of the stove; Fig. 7 a longitudinal vertical central sectional view of'the modified form of the stove; Fig. 8, a trans verse sectional view on the line B B in Fig. 7 and, Fig. 9, a horizontal sectional viewon the line C C in Fig. 6.

Similar reference characters throughout the various figures of the drawings designate "like parts or features of construction.

In Figs. 1 to 5 inclusive the invention is illustrated as being adapted for larger sizes when the maximum amount 0f heated air is required to be carried ofi for heating purposes, the stove comprising a suitable base at having an ash-pit aand a hearth plate a" .to permit of the removal of ashes, and a body partnis suitably ,mounted on the base and comprises a front bprovided with a fire door 0, and a back at, the front and back being preferablycomposed of cast iron. A false front 6 is attached tothe front 1) against the V upper-portion thereof and with the front 6 forms a chamber to receive heated air for distribution. The body part comprises also two vertical sides f and f and an arched top 9 preferablyformed integral with the sides, and all suitably joined to the front 7) and backoZ-with the sides on the base a. The front I) and back 03 and the base or preferably have joint flanges or ribs as is usual. The combustion chamber has two side walls 72. and h spaced a suitable distance from the sides f and f, and a roof plate 1' preferably formed integralwith the side walls, the side walls. and roof plate extending from the front I; to the back cl and suitably. joined thereto. The air chamber is formed partly by the walls 71, and h and roof plate 1 and by two vertical walls j and j that are arranged between the combustion chamber walls and the sides f and f of the body part, the walls '7' and. j being formed of metal and turned inward at thelr lower portions and joined tothe lower edgesof the walls h and it, so that draft fines or passages are provided that extend under the walls h and h and under the walls j and j, and upward between the sides f and f and the walls j and j, there being a roof plate 70 preferably formed integral with the walls j and j above theroof plate 2'. The front 5 has two inlet openings Z :and Z therein communicating with the air chamber'at the lower portions thereof, and the back d has two inlet openings m, and m opposite to the openings Z and Z'to admit air to be heated in the air chamber. If preferred, however, one or more of arranged in the front 1) within the chamber I formed by the false front a. v

More or less space is provided between the air chamber roof is and the top g of the body part, and a suitable number of air fines are arranged therein that extend from the front Z) to the back cl, there being two fiues 0 and 0 arranged above the roof is near the sides 7' and f, the fiues being slightly separated one from the other. The fines are preferably oblong in section and arranged with their greater diameters in horizontal planes. A similar but broader fiue p is arranged above the fines '0 and 0 and spaced midway be tween the sides f and f, and two other fines g and g are arranged above the flue p similarly to the arrangement of the fiues 0 and 0, and yet another fiue r is arranged above the lines 9 and g. All the air fines have communicating openings or passages n so that heated air may pass from the tines into the chamber formed by the false front 0. The back (Z has suitable openings at to admit air to the air fines. A pair of draft shutters s and s are arranged on operating rods t at opposite sides of the flue r, so that the draft passage between the fiue and the top 9 may be entirely or partially closed as desired at either side of the fiue r, so that when one shutter is closed, the greater amount of heat will be given off from the opposite side of the stove which may be desirable in cases when the stove must of necessity be placed Where it may be desired to obtain more heat from one side than from the other side thereof, the shutters being provided with operating handles 3 at the rear of the back (Z; The stove is provided with a chimney connection a connected at an opening a in the top 0, and a distributing pipe 2; is connected at an opening of in the top of the false front 6 to carry off the heated air for distribution to other rooms or apartments. The back (Z has a suitable number of openings r0 therein each arranged slightly higher than the air fiues, so that scrapers may be inserted to scrape soot from the tops of the fines, there being an opening also for cleaning the roof I: of the air chamber, the openings being normally closed by gates w pivoted on the back (Z.

In Figs. 6 to 9 inclusive is illustrated the modified form of stove which is designed to be built in the smaller sizes and has somewhat less capacity for heating air than with the construction h-ereinbefore described, the lower portions of the stove being substantially the same in all cases. In the modified form as shown, the base a is employed and a front I) and back d "of suitable shapes, the front having a door 0. Sides 7 and f have inwardly inclined upper portions y and 1 and vertical portions '2 and 2 extending upward a short distance from the inclined portions, a top 9 resting on the tops of the side portions 2 and z. The air chamber is formed partly by the side walls l1 and h and roof plate i and partly by the walls j and j which have inwardly extending inclined upper portions 10 and 10, and top portions 11 and 11 connected by a roof plate 12. The front Z) has an outlet opening 13 connected to a distributing pipe 14, and the back cl has an outlet opening 13 connected to a distributing pipe 14;, for conveying the heated air away from the top of the air chamber for use. The front Z) has also the inlet openings Z and Z, and the back (1 has the inlet openings m and m to admit air at the bottom of the air chamber to be h rated. Bearing plates 15 and 15 are secured in the draft passages preferably near the upper parts of the portions 11 and 11 of the walls, and a shutter 16 is mounted in one plate and in connection with the front I) and has an operating handle 16, so that the draft may be shut off from one portion of the draft passage. Also a shutter 17 is mounted in the bearing plate and also .in the back d and has an operating handle 17. A shutter .18 is mounted in the other bearing plate and in the front I), and has an operating handle 18, and still another shutter 19 is mounted in the bearing plate and in the back 03 and has an operating handle 19. The shutters are rotative, as will be understood, and may be turned so as to either partially or entirely close a portion of the draft passage, so that if desired, the heat radiation may be decreased at either side of the stove. It will be understood of course that the stove may be slightly modified so as to permit of the use of any kind of fuel desired.

In practical use, the fuel will be consumed either in the ash-pit a or on suitable grates if preferred, and the walls and roof of the combustion chamber will be highly heated so that air at the sides and above the combustion chamber will also become highly heated, and as the draft currents pass around the sides and top of the air chamber, the heat from the escaping gases will also be imparted to some extent to the air in the air chamber, while some of the heat will, be radiated by the outer wall of the stove before escaping from the opening a in the top g or into the chimney connection a. TV hen fires are being started, it is preferable to open the shutters until relatively perfect combustion occurs, after which one ormore of the shutters may be closed, if desired.

Having thus described the invention, what is claimed as new is 1. A stove comprising a base, a front wall on the base, a door mounted on the front wall, a back wall on the base, a body part having side walls and a top connected to the front and back walls, the side walls being attached to the base, and the top having a. d aft opening therein, a combustion chamber wall, a back on the'base, a body part having side walls and a top connected to the front and back, the sidewalls being attached to the base, and the top having a draft opening therein, a combustion chamber having two side walls and a roof plate attached to the front and back walls, the walls being clear of the base, an air-chamber formed by walls between the walls of the body part and the walls of the combustion chamber and by a.

roof plate extending above the roof plate of the combustion chamber,-theair-chamber having inlet openings and outlet openings, a plurality of air-flues above the air-chamber extending from the front wall to the back wall, the fiues being open at theirends, and a false front attached to the front wall to form a chamber at the outlet endsof the air fiues and at the outlet openings of the airtop connected to the front and back walls and therewith forming walls of draft passages, the side walls being attached to the base, and the top having a draft opening therein, a combustion chamber having two side walls and a roof plate attached to the front and back walls, the side walls being clear of the base, an air-chamberformed by walls between the walls of the body part and the walls of the combustion chamber, the walls of the air-chamber forming parts of the draft passages, said air-chamber having inlet openings and outlet openings, and closures on said back wall opposite said cleaning openings. 7

In testimony whereof, I affix my signature in presence of two Witnesses.
